Slowing of global warming officially confirmed — by reading between the lines

Posted by Henry Bauer on 2017/08/12

Climate-change skeptics, deniers, denialists, and also unbiased observers have pointed out that measured global temperatures seem to have risen at a slower rate, or perhaps ceased rising at all, since about 1998.
But the media have by and large reported the continuing official alarmist claims that each year has been the hottest on record, that a tipping point is nearly upon us, catastrophe is just around the corner — exemplified perhaps by Al Gore’s recent new film, An Inconvenient Sequel, with interviews of Gore in many media outlets.

However, that the pause in global warming is quite real is shown decisively by the way in which the mainstream consensus has tried to discount the facts, attempting to explain them away.
For example a pamphlet, published jointly by the Royal Society of London and the National Academy of Sciences of the USA, asserts that human-caused release of greenhouse gases is producing long-term warming and climate change, albeit there might be periods on the order of decades where there is no or little warming, as with the period since about 2000 when such natural causes as “lower solar activity and volcanic eruptions” have “masked” the rise in temperature (“Climate-Change Science or Climate-Change Propaganda?”).

That assertion misses the essential point: All the alarmist projections are based on computer models. The models failed to foresee the pause in temperature rise since 1998, demonstrating that the models are inadequate and therefore their projections are wrong. The models also fail to accommodate the period of global cooling rather than warming from the 1940s to the 1970s.

The crux is that the models do not incorporate important natural forces that affect the carbon cycle and the energy interactions. Instead, when the models are patently wrong, as from 1940s to 1970s and since 1998, the modelers and other researchers vested in the theory of human-caused climate change speculate about how one or other natural phenomenon somehow “masks” the asserted underlying temperature rise.

Above all, of course, the theorists neglect to mention that the Earth is still rebounding from the last Ice Age and will, if the last million years are any guide, continue to warm up for many tens of thousands of years (Climate-change facts: Temperature is not determined by carbon dioxide).
The various attempts to explain away the present pause in temperature rise were listed a few years ago at THE HOCKEY SCHTICK“Updated list of 66 excuses for the 18-26 year ‘pause’ in global warming — ‘If you can’t explain the ‘pause’, you can’t explain the cause’”.
Here are a few of the dozens of excuses for the failure of global temperature to keep up with projections of the climate models:

1. Lower activity of the sun
That ought to raise eyebrows about this whole business. Essentially all the energy Earth receives from out there comes from the Sun. Apparently the computer models do not start by taking that into account?
(Peter Stauning, “Reduced solar activity disguises global temperature rise”, Atmospheric and Climate Sciences, 4 #1, January 2014 “Without the reduction in the solar activity-related contributions the global temperatures would have increased steadily from 1980 to present”)
And of course if the Sun stopped shining altogether…
Anyway, the models are wrong.

2. The heat is being hidden in the ocean depths (Cheng et al., “Improved estimates of ocean heat content from 1960 to 2015”, Science Advances, 10 March 2017, 3 #3, e1601545, DOI: 10.1126/sciadv.160154
In other words, the models are wrong about the distribution of supposedly trapped heat.

3. Increased emission of aerosols especially in Asia (Kühn et al., “Climate impacts of changing aerosol emissions since 1996”, Geophysical Research Letters, 41 [14 July 2014] 4711–18, doi:10.1002/2014GL060349)
The climate models are wrong because they do not properly take aerosol emissions into account.

3a. “Volcanic aerosols, not pollutants, tamped down recent Earth warming, says CU study”
       In other words, the models are wrong because they cannot take into account the complexities of natural events that affect climate.

4. Reduced emission of greenhouse gases, following the Montreal Protocol eliminating ozone-depleting substances (Estrada et al, “Statistically derived contributions of diverse human influences to twentieth-century temperature changes”, Nature Geoscience, 6 (2013) 1050-55 doi:10.1038/ngeo1999
       The climate models are wrong because they do not take into account all greenhouse-gas emissions.

5. “Contributions of stratospheric water vapor to decadal changes in the rate of global warming” (Solomon et al., Science, 327 [2010] 1219-12;
DOI: 10.1126/science.1182488)
In other words, the models are wrong because they do not take account of variations in water vapor in the stratosphere.

6. Strengthened trade winds in the Pacific
Again, the models are wrong because they cannot take account of the innumerable natural phenomena that determine climate.

6a.     An amusing corollary is that “Seven years ago, we were told the opposite of what the new Matthew England paper says: slower (not faster) trade winds caused ‘the pause’”

And so on though another 50 or 60 different speculations. Although they are all different, there is a single commonality: The computer models used to represent Earth’s climate are woefully unable to do so. That might well be thought to be obvious a priori in view of the astronomical number of variables and interactions that determine climate. Moreover, a little less obviously perhaps, “global” climate is a human concept. The reality is that short- and long-term changes in climate by no means always occur in parallel in different regions.

Take-away points:

Mainstream climate science has demonstrated that
all the climate models are inadequate
and their projections have been wrong

Since the late 1990s, global temperatures have not risen
to the degree anticipated by climate models and climate alarmists
but that is not officially admitted
even as it is obvious from the excuses offered
for the failure of the models

Superstitious belief in science

Posted by Henry Bauer on 2017/05/16

Most people have a very misled, unrealistic view of “science”. A very damaging consequence is that scientific claims are given automatic respect even when that is unwarranted — as it always is with new claims, say about global warming. Dramatic changes in how science is done, especially since mid-20th century, make it less trustworthy than earlier.

In 1987, historian John Burnham published How Superstition Won and Science Lost, arguing that modern science had not vanquished popular superstition by inculcating scientific, evidence-based thinking; rather, science had itself become on worldly matters the accepted authority whose pronouncements are believed without question, in other words superstitiously, by society at large.

Burnham argued through detailed analysis of how science is popularized, and especially how that has changed over the decades. Some 30 years later, Burnham’s insight is perhaps even more important. Over those years, certain changes in scientific activity have also become evident that support Burnham’s conclusion from different directions: science has grown so much, and has become so specialized and bureaucratic and dependent on outside patronage, that it has lost any ability to self-correct. As with religion in medieval times, official pronouncements about science are usually accepted without further ado, and minority voices of dissent are dismissed and denigrated.

A full discussion with source references, far too long for a blog post, is available here.

Climate-change orthodoxy: alternative facts, uncertainty equals certainty, projections are not predictions, and other absurdities of the “scientific consensus”

Posted by Henry Bauer on 2017/05/10

G. K. Chesterton once suggested that the best argument for accepting the Christian faith lies in the reasons offered by atheists and skeptics against doing so. That interesting slant sprang to mind as I was trying to summarize the reasons for not believing the “scientific consensus” that blames carbon dioxide for climate change.

Of course the very best reason for not believing that CO2 causes climate change are the data, as summarized in an earlier post

–>      Global temperatures have often been high while CO2 levels were low, and vice versa

–>     CO2 levels rise or fall after temperatures have risen or fallen

–>     Temperatures decreased between the 1940s and 1970s, and since about 1998 there has been a pause in warming, perhaps even cooling, while CO2 levels have risen steadily.

But disbelieving the official propaganda becomes much easier when one recognizes the sheer absurdities and illogicalities and self-contradictions committed unceasingly by defenders of the mainstream view.

1940s-1970s cooling
Mainstream official climate science is centered on models: computer programs that strive to simulate real-world phenomena. Any reasonably detailed description of such models soon reveals that there are far too many variables and interactions to make that feasible; and moreover that a host of assumptions are incorporated in all the models (1). In any case, the official models do not simulate the cooling trend of these three decades.
“Dr. James Hansen suspects the relatively sudden, massive output of aerosols from industries and power plants contributed to the global cooling trend from 1940-1970” (2).
But the models do not take aerosols into account; they are so flawed that they are unable to simulate a thirty-year period in which carbon emissions were increasing and temperatures decreasing. An obvious conclusion is that no forecast based on those models deserves to be given any credence.

One of the innumerable science-groupie web-sites expands on the aerosol speculation:
“40’s to 70’s cooling, CO2 rising?
This is a fascinating denialist argument. If CO2 is rising, as it was in the 40’s through the 70’s, why would there be cooling?
It’s important to understand that the climate has warmed and cooled naturally without human influence in the past. Natural cycle, or natural variability need to be understood if you wish to understand what modern climate forcing means. In other words modern or current forcing is caused by human industrial output to the atmosphere. This human-induced forcing is both positive (greenhouse gases) and negative (sulfates and aerosols).”

Fair enough; but the models fail to take account of natural cycles.

Rewriting history
The Soviet Union had an official encyclopedia that was revised as needed, for example by rewriting history to delete or insert people and events to correspond with a given day’s political correctness. Some climate-change enthusiasts also try to rewrite history: “There was no scientific consensus in the 1970s that the Earth was headed into an imminent ice age. Indeed, the possibility of anthropogenic warming dominated the peer-reviewed literature even then” (3). Compare that with a host of reproductions and citations of headlines from those cold times when media alarms were set off by what the “scientific consensus” indeed then was (4). And the cooling itself was, of course, real, as is universally acknowledged nowadays.

The media faithfully report what officialdom disseminates. Routinely, any “extreme” weather event is ascribed to climate change — anything worth featuring as “breaking news”, say tsunamis, hurricanes, bushfires in Australia and elsewhere. But the actual data reveal no increase in extreme events in recent decades: not Atlantic storms, nor Australian cyclones, nor US tornadoes, nor “global tropical cyclone accumulated energy”, nor extremely dry periods in the USA, in the last 150 years during which atmospheric carbon dioxide increased by 40% (pp. 46-51 in (1)). Nor have sea levels been rising in any unusual manner (Chapter 6 in (1)).

Defenders of climate-change dogma tie themselves in knots about whether carbon dioxide has already affected climate, whether its influence is to be seen in short-term changes or only over the long term. For instance, the attempt to explain 1940s-70s cooling presupposes that CO2 is only to be indicted for changes over much longer time-scales than mere decades. Perhaps the ultimate demonstration of wanting to have it both ways — only long-term, but also short-term — is illustrated by a pamphlet issued jointly by the Royal Society of London and the National Academy of Science of the USA (5, 6).

No warming since about 1998
Some official sources deny that there has been any cessation of warming in the new century or millennium. Others admit it indirectly by attempting to explain it away or dismiss it as irrelevant, for instance “slowdowns and accelerations in warming lasting a decade or more will continue to occur. However, long- term climate change over many decades will depend mainly on the total amount of CO2 and other greenhouse gases emitted as a result of human   activities” (p. 2 in (5)); “shorter-term variations are mostly due to natural causes, and do not contradict our fundamental understanding that the long-term warming trend is primarily due to human-induced changes in the atmospheric levels of CO2 and other greenhouse gases” (p. 11 in (5)).

Obfuscating and misdirecting
The Met Office, the UK’s National Meteorological Service, is very deceptive about the recent lack of warming:

“Should climate models have predicted the pause?
Media coverage … of the launch of the 5th Assessment Report of the IPCC has again said that global warming is ‘unequivocal’ and that the pause in warming over the past 15 years is too short to reflect long-term trends.

[No one disputes the reality of long-term global warming — the issue is whether natural forces are responsible as opposed to human-generated carbon dioxide]

… some commentators have criticised climate models for not predicting the pause. …
We should not confuse climate prediction with climate change projection. Climate prediction is about saying what the state of the climate will be in the next few years, and it depends absolutely on knowing what the state of the climate is today. And that requires a vast number of high quality observations, of the atmosphere and especially of the ocean.
On the other hand, climate change projections are concerned with the long view; the impact of the large and powerful influences on our climate, such as greenhouse gases.

[Implying sneakily and without warrant that natural forces are not “large and powerful”. That is quite wrong and it is misdirection, the technique used by magicians to divert attention from what is really going on. By far the most powerful force affecting climate is the energy coming from the sun.]

Projections capture the role of these overwhelming influences on climate and its variability, rather than predict the current state of the variability itself.
The IPCC model simulations are projections and not predictions; in other words the models do not start from the state of the climate system today or even 10 years ago. There is no mileage in a story about models being ‘flawed’ because they did not predict the pause; it’s merely a misunderstanding of the science and the difference between a prediction and a projection.
[Misdirection again. The IPCC models failed to project or predict the lack of warming since 1998, and also the cooling of three decades after 1940. The point is that the models are inadequate, so neither predictions nor projections should be believed.]

… the deep ocean is likely a key player in the current pause, effectively ‘hiding’ heat from the surface. Climate model projections simulate such pauses, a few every hundred years lasting a decade or more; and they replicate the influence of the modes of natural climate variability, like the Pacific Decadal Oscillation (PDO) that we think is at the centre of the current pause.
[Here is perhaps the worst instance of misleading. The “Climate model projections” that are claimed to “simulate such pauses, a few every hundred years lasting a decade or more” are not made with the models that project alarming human-caused global warming, they are ad hoc models that explore the possible effects of variables not taken into account in the overall climate models.]”

The projections — which the media (as well as people familiar with the English language) fail to distinguish from predictions — that indict carbon dioxide as cause of climate change are based on models that do not incorporate possible effects of deep-ocean “hidden heat” or such natural cycles as the Pacific Decadal Oscillation. Those and other such factors as aerosols are considered only in trying to explain why the climate models are wrong, which is the crux of the matter. The climate models are wrong.

Asserting that uncertainty equals certainty
The popular media disseminated faithfully and uncritically from the most recent official report that “Scientists are 95% certain that human are responsible for the ‘unprecedented’ warming experienced by the Earth over the last few decades

Leave aside that the warming cannot be known to be “unprecedented” — global temperatures have been much higher in the past, and historical data are not fine-grained enough to compare rates of warming over such short time-spans as mere decades or centuries.

There is no such thing as “95% certainty”.
Certainty means 100%; anything else is a probability, not a certainty.
A probability of 95% may seem very impressive — until it is translated into its corollary: 5% probability of being wrong; and 5% is 1 in 20. I wouldn’t bet on anything that’s really important to me if there’s 1 chance in 20 of losing the bet.
So too with the frequent mantra that 97% or 98% of scientists, or some other superficially impressive percentage, support the “consensus” that global warming is owing to carbon dioxide (7):

 

“Depending on exactly how you measure the expert consensus, it’s somewhere between 90% and 100% that agree humans are responsible for climate change, with most of our studies finding 97% consensus among publishing climate scientists.”

In other words, 3% (“on average”) of “publishing climate scientists” disagree. And the history of science teaches unequivocally that even a 100% scientific consensus has in the past been wrong, most notably on the most consequential matters, those that advanced science spectacularly in what are often called “scientific revolutions” (8).
Furthermore, “publishing climate scientists” biases the scales a great deal, because peer review ensures that dissenting evidence and claims do not easily get published. In any case, those percentages are based on surveys incorporating inevitable flaws (sampling bias as with peer review, for instance). The central question is, “How convinced are you that most recent and near future climate change is, or will be, the result of anthropogenic causes”? On that, the “consensus” was only between 33% and 39%, showing that “the science is NOT settled” (9; emphasis in original).

Science groupies — unquestioning accepters of “the consensus”
The media and countless individuals treat the climate-change consensus dogma as Gospel Truth, leading to such extraordinary proposals as that by Professor of Law, Philippe Sands, QC, that “False claims from climate sceptics that humans are not responsible for global warming and that sea level is not rising should be scotched by an international court ruling”.

I would love to see any court take up the issue, which would allow us to make defenders of the orthodox view attempt to explain away all the data which demonstrate that global warming and climate change are not driven primarily by carbon dioxide.

The central point

Official alarms and established scientific institutions rely not on empirical data, established facts about temperature and CO2, but on computer models that are demonstrably wrong.

Those of us who believe that science should be empirical, that it should follow the data and change theories accordingly, become speechless in the face of climate-change dogma defended in the manner described above. It would be screamingly funny, if only those who do it were not our own “experts” and official representatives (10). Even the Gods are helpless in the face of such determined ignoring of reality (11).

Trust science at your peril: Beware of scientism and political correctness

Posted by Henry Bauer on 2016/06/25

Science is, ideally, a quest for authentic understanding of the world, of everything in the universe. Scientism is a religious faith which preaches that only science is capable of gaining such authentic understanding and that contemporary scientific claims are for all practical purposes true.

In reality, science is a perpetually unfinished quest. The history of science tells of false trails followed, of errors made, of misguided theories held dogmatically long after the evidence had turned against them, of researchers motivated by self-interest and influenced — corrupted, in a sense — by conflicts of interest.

Science has progressed marvelously, but the progress has not come steadily and linearly, it has come through continual correction of minor errors as well as periodic scientific revolutions in which former dogmas were discarded and replaced by different theories, different beliefs, different dogmas, sometimes to an extent capable of changing world-views.

Those realities have been described and documented in many articles and books over many decades (1), yet the conventional wisdom seems ignorant of them. In the popular view, science deploys the scientific method which guarantees getting things right through scrupulous adherence to facts, so that the scientific consensus on any given topic at any given time can supposedly be relied on quite safely to guide personal and public actions.

People who question the mainstream view, the official positions disseminated by such bodies as the National Academy, the Royal Society of London, the National Science Foundation, the National Institutes of Health, the Food and Drug Administration, the World Health Organization, etc., are dismissed as ignoramuses on a par with those who still believe that the Earth is flat, and they are denigrated, attacked, and suppressed as “denialists” — for example, the eminently qualified scientists who question whether HIV really causes AIDS (2), or whether carbon dioxide is the prime cause of global warming (3), or whether the universe began in a Big Bang about 13 billion years ago (4).

In other words, the officially accepted conventional wisdom functions as an exercise of scientism, proclaiming as true — as not to be questioned — any contemporary claims that have the imprimatur of a prevailing scientific consensus.

The most common popular, mass-media-disseminated beliefs about science fall in line with the official scientistic conventional wisdom. Prominent popularizers of the scientistic faith include people sometimes described as the “New Atheists” — see for instance Curtis White in The Science Delusion (Melville House, 2014), who names among others Richard Dawkins, Daniel Dennett, Sam Harris, Bill Mahler. Self-styled “Skeptics” (for instance Michael Shermer and the late Martin Gardner) are also apostles of scientism, as illustrated in associated publications (Skeptic, Skeptical Inquirer).

But promiscuously indiscriminate faith in currently accepted scientific knowledge is unwarranted. One does not need the immense scholarly literature (1) to recognize that, it is already obvious from first principles and fundamental logic:

–>      Science is carried out by human beings and is therefore inherently fallible.

–>      Scientific theories are neither uniquely determined nor proved by any amount of factual evidence. The proverbial black swans demonstrate that no matter how comprehensive or long-standing any given body of evidence and associated explanations may be, no matter that an hypothesis may have been thoroughly tested and accepted via the scientific method, there may remain lurking in the unknown unknown some bits of data that can disprove the accepted theory instantly and devastatingly.

The popular adherence to scientistic dogmas is immensely dangerous because it may support public policies that cause tangible damage, sometimes on a large scale. Historical examples are fairly well known, but their lesson has not been learned; perhaps because a corollary of contemporary scientistic faith seems to be the notion, implicit if not explicit, that even if science was fallible in earlier times, today’s science is so advanced, so sophisticated, that it is no longer dangerously fallible. That and similar corollaries are acts of faith unsupported by evidence, thereby confirming that scientism is a quasi-religious faith: it is unshakeable, embraced as absolutely and self-evidently true.

A couple of recent books (5) describe the considerable damage done by public policies based on a scientific consensus which remained active during something like half of the 20th century: the policies of forced sterilization of purportedly feeble-minded individuals. This was an exercise in eugenics, a program intended to improve the national genetic stock, and it was supported and justified by the prevailing scientific consensus.

In reviewing these books, David Oshinsky focuses on the Supreme Court’s 8-to-1 decision in 1927, written by the revered Oliver Wendell Holmes Jr. and agreed to by the “liberal” Jewish Louis Brandeis as well as by 6 other Associate Justices, upholding the forced sterilization of those judged to be mentally defective: “Was it an isolated misstep or something more: an indictment of Justice Holmes and the Progressive movement he appeared to embrace?” (6).

Oshinsky describes the IMBECILES book by Cohen as “a superb history of eugenics in America, from its beginnings as an offshoot of social Darwinism — human survival of the fittest — to its rise as a popular movement, advocating the state-sponsored sterilization of ‘feeble­minded, insane, epileptic, inebriate, criminalistic and other degenerate persons’.”

The point I want to make here is that the forced sterilization of tens of thousands of Americans, which continued in some States into the 1960s, is nowadays described as an outrage based on pseudo-science, yet it had relied on what was regarded at the time as perfectly sound science supported fervently by individuals whose reputation remains that of progressive reformers: as well as Justices Holmes and Brandeis, strong advocates of this eugenic program included other “progressive icons like Theodore Roosevelt and the birth control champion Margaret Sanger . . . . people who combined ‘extravagant faith in science and the state with an outsized confidence in their own expertise.’ . . . Science didn’t lie” (6).

This notion that science doesn’t lie, that it can always be believed, is a tenet of scientism, and it is baseless, quite wrong, as already noted. Yet this notion, this subconscious scientism continues to corrupt public discourse. Scientism is a faith held unwittingly by most popular media, including such elites as the New York Times; and it is held, again unwittingly, by today’s sociopolitical progressives or liberals.

When some claims by some scientists seem plausibly consistent with liberal, progressive programs, activists seize on them, make dogmas of the claims, and denigrate and attack those who disagree as unscientific denialists.

This circumstance is what has come to be called in recent decades “political correctness”: certain views are to be accepted as so self-evidently correct, objectively true — and by the way ethically and morally sound — that disagreeing with them is virtually a criminal act; and indeed actions that are politically incorrect may bring sanctions. Contemporary illustrations of such sanctions are the penalties imposed by colleges and universities on students and faculty who make politically incorrect statements, including the mere use of a word or a phrase that acts as a “trigger”, a “micro-aggression” that makes some individual belonging to a certified-discriminated-against minority feel uncomfortable (7).

That something is politically correct is shown when people who have no direct specific knowledge about a topic express with certainty a dogmatic opinion about it. They have obviously taken this opinion on faith, from sources congenial to them on ideological grounds, which may be based religiously, socially, politically — at any rate, not on actual evidence about the matter.

Contemporary scientific claims that have attained the status of politically correct include that HIV causes AIDS and that human-caused liberation of carbon dioxide is the prime cause of climate change. The manner in which media and individuals refer to these matters is an immediate proof that opinions about them are politically correct, not evidence-based.

For example, the vigilantes who most assiduously and viciously attack those who question whether HIV causes AIDS include an economist (Nicoli Nattrass), a graduate student (Ken Witwer), a psychologist (Seth Kalichman), a lawyer (Jeanne Bergman), an activist (Nathan Geffen) and others, all of whom feel qualified, despite their lack of appropriate qualifications, to denigrate eminent molecular biologists with deep knowledge of the subject, and even to demand that the National Library of Medicine remove a journal from MEDLINE (8).

Left-leaning media (say, MSNBC) treat HIV=AIDS as indisputable settled science; right-leaning media (say, Fox News) doubt that HIV causes AIDS.

Left-leaning media treat as indisputably settled science that human activities are responsible for global warming and climate change; right-leaning media doubt or deny that.

Nature, however, will not be mocked, and the truth is not determined by human ideologies. Public policies (and also private actions, of course) had best be based on the soundest, most probing and skeptical assessment of current knowledge-claims in light of the indisputable fact that no contemporary scientific consensus represents guaranteed truth.

If the present scientistic, politically correct beliefs about HIV/AIDS and about climate change are as misguided as were the scientistic, politically correct beliefs about mental deficiency and eugenics, then immense harm is being done and will continue to be done. Unfortunately, the plain evidence is that HIV does not cause AIDS (9, 10), and the notion that human activities are responsible for global warming and climate change is suggested only by highly complicated, sophisticated, and fallible computer programs that have already been wrong about the global cooling in the 1940s to 1970s and the lack of appreciable warming since about 2000 (4).

Forced sterilization as part of a eugenic program to improve the fitness of the population was supported by progressive reformers and by eminent medical and scientific experts. That physical traits are transmitted from one generation to another was known, scientifically as well as popularly. That behavioral characteristics are similarly transmitted was not obviously wrong, and when sanctioned by experts it became the conventional wisdom. So feeble-minded-ness, epilepsy, poverty, criminality and other socially undesirable characteristics came to be targets for elimination, by quarantining or sterilizing people and families where such characteristics had been noted (11). There was not sufficient dissent within expert communities to prevent what is now recognized as pseudo-science from becoming accepted as settled science, during the early decades of the 20th century: “Less than 100 years ago, America’s finest minds were convinced the nation was threatened by sexually insatiable female morons” (12). Those finest minds included, as well as the earlier mentioned progressive reformers, David Starr Jordan, a biologist specializing in ichthyology, an activist for peace, an eminent educator — president of Indiana University and later founding president of Stanford University — and moreover so concerned with distinguishing good science from bad science and pseudo-science that he had written a book about it (13), as well as works about eugenics (14).

So policy makers might be excused for succumbing to the “scientific” evidence supporting eugenics — a century ago. Nowadays, though, there is no similar excuse for sticking with the theory of HIV/AIDS or with the claim that it is indisputably settled science that global warming and climate change are humanly caused. Competent, qualified experts have published and spoken copiously, pointing to the deficiencies of the present scientific consensuses on these matters. It is past time that these whistle-blowers, these “denialists”, be attended to; that the actual evidence be attended to.

Climate change “deniers”

Posted by Henry Bauer on 2015/10/16

Very good piece, “Climate change denier silenced for doing Climate Science and disagreeing with the science“.

“Philippe Verdier, weather chief at France Télévisions” is the lead in to the story, but it also cites Freeman Dyson, greatly respected physicist who for decades was at the Institute for Advanced Study in Princeton:
“‘It’s very sad that in this country, political opinion parted [people’s views on climate change],’ he said, in an interview with The Register. ‘I’m 100 percent Democrat myself, and I like Obama. But he took the wrong side on this issue, and the Republicans took the right side.'”

Precisely my view: “A politically liberal global-warming skeptic?”.

Psychological toll of climate-science belief

Posted by Henry Bauer on 2015/07/11

Mountainmere  just drew our attention to the devastating psychological impact of belief in human-caused climate change.

Esquire carried (7 July) a story by John Richardson, “When the End of Human Civilization Is Your Day Job: Among many climate scientists, gloom has set in. Things are worse than we think, but they can’t really talk about it” — they are afraid to talk about it because of “the relentless campaign against them” in which the poor folk are labeled “alarmist”. (The heartbreaking Richardson story was picked up in a number of places, for instance “Climate Scientists Are Dealing with Psychological Problems”  as well as the Judith Curry blog that mountainmere had cited, “Pre-traumatic stress syndrome: climate scientists speak out”.)
If climate “scientists” want to know what a relentless campaign really looks like, they should examine the treatment meted out to those “denialists” who draw attention to the lack of evidence to support the hypothesis of human-caused global warming.

Richardson’s featured climate-scientist victim, Jason Box, is a stereotypical ultra-environmentalist: an American who has worked for Greenpeace, demonstrated at the White House, claimed that sea levels would rise inevitably by 70 feet in the next few centuries, and “escaped America’s culture of climate-change denial” by moving from Ohio to Denmark. A report of methane seeping into Arctic sea-water so terrified Box that he immediately tweeted “If even a small fraction of Arctic sea floor carbon is released to the atmosphere, we’re f’d”, which naturally brought a flurry of headlines.
Box looks at the worst, and among the least likely, of the various scenarios generated by the computer models used by climate “scientists” — models that have been demonstrably wrong for the last 15-18 years or so during which there has been no warming while carbon dioxide levels have continued to rise; models that fail to account for the 1940s-to-1970s period when global temperatures were actually decreasing while carbon-dioxide levels were steadily rising.
Box thinks “most scientists must be burying overt recognition of the awful truths of climate change in a protective layer of denial (not the same kind of denial coming from conservatives, of course). I’m still amazed how few climatologists have taken an advocacy message to the streets, demonstrating for some policy action.”

Richardson’s story is full of errors, notably that “warming is tracking the rise of greenhouse gases exactly as their models predicted”. No. The models have not predicted the empirical fact that global temperatures have been stable rather than rising since about 2000; some reports even have it as a cooling rather than a slowing or halt in global average temperature: http://isthereglobalcooling.com; http://wattsupwiththat.com/2012/01/11/the-portland-state-university-study-of-shrinking-mt-adams-glaciersa-good-example-of-bad-science; http://notrickszone.com/2013/09/12/no-warming-left-to-deny-global-cooling-takes-over-cet-annual-mean-temperature-plunges-1c-since-2000/#sthash.mowZKMjF.dpbs; http://www.forbes.com/sites/peterferrara/2013/05/26/to-the-horror-of-global-warming-alarmists-global-cooling-is-here; http://www.globalresearch.ca/global-cooling-is-here/10783.

Richardson describes the terrible stress that climate scientists are under for bringing their message of lack of hope: “targets of an unrelenting and well-organized attack that includes death threats, summonses from a hostile Congress, attempts to get them fired, legal harassment, and intrusive discovery demands so severe they had to start their own legal-defense fund, all amplified by a relentless propaganda campaign nakedly financed by the fossil-fuel companies”.
It’s just as well that they can continue to do their depressing work with the help of large grants and that any attempts to have them fired went nowhere; and that the “intrusive discovery demands” were no more than to ask for the raw data on which Michael Mann conjured his alarmist “hockey-stick” graph of unprecedented rate of warming — a graph that the Intergovernmental Panel on Climate Change dropped from its Reports because it was shown to be not a valid reorientation of the data. Professional scientific journals have increasingly being demanding that all data on which articles are based need to be made publicly available; it is not clear to me why climate “science” should be exempt. The only reason to keep data secret is to avoid that others could show that published analyses are flawed.
And those poor climate scientists suffered from having their e-mails hacked, revealing that they were deliberately fudging the evidence. (Google “Climategate” for details about that.)

So, anyway, those poor activist climate “scientists” are suffering gloom, sadness, fear, anger; “Dr. Lise Van Susteren, a practicing psychiatrist and graduate of Al Gore’s Inconvenient Truth slide-show training, calls this ‘pretraumatic’ stress.” Some are retreating off the grid to await the catastrophe. “No one has experienced that hostility more vividly than Michael Mann”, who barley manages to keep going as a well-paid tenured full professor at Penn State.

I urge you to read Richardson’s full story, especially the later parts that describe all the suffering that climate scientists endure.

For yet more insight, go to Judith Curry’s earlier blog post, “Pre-traumatic stress syndrome: Climate trauma survival tips”  which informs, among other things, about “the relatively new field of psychology of global warming”; followed by Curry’s sensible deconstruction of climate-change hysteria.

The unfortunate pre-traumatically stressed climate-“science” activists suffer quite unnecessarily. I recommend resort to the school of psychology, “rational-emotive therapy”, associated with the name of Albert Ellis; see his A New Guide to Rational Living, or Help yourself to happiness through rational self-counseling by Macie C. Maultsby, an acolyte of Ellis.
The essence of this approach is to list in writing one’s depressing thoughts, and then the emotions they arouse. Merely writing these down tends to reveal how out of all proportion the emotions are. Then, the really important part, annotate those depressing thoughts with the actual evidence.
With climate “scientists”, this should bring immediate relief, since all their depression arises only from computer models, whereas reality demonstrates that global warming is the result of the Earth recovering from the last Ice Age and that carbon dioxide has no appreciable effect, as proven by the periods from the 1940s to the 1970s and again since 2000, when “carbon” was being emitted relentlessly but Earth warmed not at all or even cooled.

Who looks at evidence? Almost no one

Posted by Henry Bauer on 2015/06/28

I’ve been a crank for a long time about Loch Ness Monsters, frustrated because I can’t get people to look at Tim Dinsdale’s 1960 film which shows quite clearly a huge animal swimming in Loch Ness, submerging while still throwing up a massive wake.

For more than a decade, I’ve been a crank about HIV not causing AIDS, frustrated because I can’t get people to look at the clear evidence that HIV tests don’t track something infectious, and that the numbers in plain sight on the website of the Centers for Disease Control & Prevention, rates of sexual transmission at less than 1 per 1000 acts of unprotected intercourse, mean that HIV cannot cause an epidemic.

Now I’ve become a crank about human-caused climate change, frustrated because people won’t look at the clear evidence that carbon dioxide has been increasing steadily even as the global temperature was level or dropping form the 1940s into the 1970s, when the experts were predicting an Ice Age; and as the global temperature has not increased since the end of the 1990s.

Why don’t people look at evidence?

Because, I’ve finally realized, they don’t want to risk having to change their mind. There is no positive incentive and plenty of negative incentive. It’s beyond cognitive dissonance, which is to evade the significance of evidence after having come across it. It’s obviously even better not to have come across the evidence at all.

On human-caused climate change (HCCC), disbelief is expressed loudly and publicly by “conservatives” (in my view more accurately described as reactionaries) who have that opinion for the wrong reasons, namely the belief that economic free markets are the most important thing and regulating anything is bad.

“Liberals” or “progressives”, on the other hand (who are actually not liberal or progressive but simply knee-jerk politically correct) don’t look at the evidence because they don’t need to, it’s of no interest to them, they would take their stance that humans cause environmental damage no matter what. And they maintain perfect deniability, they are blameless, they were just accepting what the authorities, the experts, have been saying loudly and incessantly.

Most of my family and friends treat my “reactionary” stance on HCCC as a minor flaw, allowing me space because I tend to get caught up in Quixotic stuff all the time. They have no interest in looking at the evidence because they are completely comfortable with the notion of HCCC because it fits their anti-reactionary political views — which I happen to share. If it turns out that this HCCC is mistaken, there would be all sorts of undesirable consequences, in particular that reactionary views might appear to have been vindicated.

I was distressed when Stephen Colbert took HCCC as proven. I am not happy when all the MSNBC crowd does so, but they’ve become too extreme for me anyway and I rarely watch. But I was very unhappy when Jon Stewart took HCCC as proven. And Pope Francis may have been the last straw (in the wind, as far as ever changing public opinion). Though I did get a sort of sardonic enjoyment from the pundits who pointed out that the Pope knew what he was talking about because he had been a chemist. And I am getting continuing Schadenfreude over the contortions of the Republican presidential candidates as they are forced to comment on the Pope’s encyclical.

Evidence-seeking, I realize, is an obsession of perhaps the tiniest minority there is. On the dangers of modern medical practice, there are just a few dozen voices crying out publicly in the wilderness. On HIV/AIDS, there is our Rethinking AIDS  group of some dozens of people, with a few thousand more quietly agreeing. On HCCC, there are a few academic types like myself who got here because of the evidence, and who subsist uncomfortably in the association with people whose political and social views we do not share, to put it mildly.

I’m beginning to accept that none of the items in my bucket list will see the light of an enlightened day within my lifetime: Nessie discovery, rejection of HIV=AIDS, rejection of carbon-dioxide-is-hurting-us.

But I do remain curious about how the “authorities” will adjust when reality eventually catches up with them irrevocably.

Anti-obesity surgery: Weight loss prevents Alzheimer’s? (Anti-obesity fuss IV)

Posted by Henry Bauer on 2014/09/05

Being obese is bad for you, so everyone is saying just now; everyone including professional societies, official agencies, and drug companies who sell mind-altering drugs to curb your appetite that may also cause “potentially life-threatening serotonin syndrome . . . . confusion, Cognitive Impairment, disturbances in attention or memory . . . , Psychiatric Disorders including euphoria and dissociation, . . . depression or suicidal thoughts” [emphasis added] as well as priapism (erections lasting longer than 4 hours) [1].

Lest this possibility of literally fatal harm suggests that the possible benefit is not worth the risk and dissuades potential customers for these drugs, we’re now told that the drugs might not only harm the brain, they could actually do the very opposite too:

“Weight-loss surgery can boost brain power and ‘cut the risk of developing Alzheimer’s’”

  • Scientists in Brazil found gastric bypass surgery can affect brain activity
  • Found the operation curbed changes in the brain associated with obesity
  • They noted improvements in planning, strategising and organising
  • Researchers also found evidence operation could reduce risk of Alzheimer’s

All this from a study of just 17 obese women, comparing them before bariatric surgery and 24 weeks after surgery.

“[S]ome areas of their [obese women’s] brains metabolised sugars at a higher rate than normal weight women. . . . in a part of the brain linked to the development of Alzheimer’s disease . . . . Since bariatric surgery reversed this activity, we suspect the procedure may contribute to a reduced risk of Alzheimer’s disease and other forms of dementia. . . .

The new research focused on a procedure known as a Roux-en-Y gastric bypass (RYBG) which combines the two types of bariatric surgery.

Brain scans and a range of psychological tests were used to assess its effect over a period of six months. . . .
bariatric surgery seemed to improve the performance of the obese women in a test of ‘executive function’. . . . the brain’s ability to connect past experience and current action . . . involved in planning, organising and making strategic decisions. Other tests measuring various aspects of memory and thinking ability showed no change after bariatric surgery”.

 

The original article on which this account is based is Marques et al., “Changes in neuropsychological tests and brain metabolism after bariatric surgery”, Journal of Clinical Endocrinology and Metabolism, 26 August 2014: jc.20142068. Its 6 pages are replete with speculation and do nothing to decrease my skepticism that lack of improvement in “various aspects of memory and thinking ability” could accompany improved performance in “planning, organising and making strategic decisions”.

This speculation is without any reasonable basis at all because Alzheimer’s Disease (AD) is far from well understood. It is simply not known that there is “a part of the brain linked to the development of Alzheimer’s disease”. There is considerable evidence against the mainstream hypothesis that AD is characterized by amyloid plaques [2].

TV’s 60 Minutes of 31 August 2014 reported results of continuing research with cohorts of old (≥90 years) people, observing their behavior and cognitive abilities together with in vivo recording of brain activity. The researchers expressed surprise that the amyloid plaques and tau tangles thought to be the cause of AD were present in some people who showed no signs of dementia; while some individuals with dementia had no sign of amyloid plaques or tau tangles. Instead, there were indications that tiny strokes had effectively killed small parts of the brain, strokes so small that the affected individual would have had no immediate indication of their occurrence.

 

Lay people might regard those findings as further evidence that amyloid and tau have nothing to do with AD, or indeed with dementia in general.
Those who believe that science rejects hypotheses when the evidence contradicts them might also imagine that the mainstream is now discarding the notion that AD is caused by accumulation of plaques of amyloid protein.

But that’s not what happens in the real world. The researchers suggested on 60 Minutes that maybe the brains of non-demented individuals with tau tangles and amyloid plaques had found some way or other to “get around” those indications of AD . . . . They didn’t try to explain why some AD victims had no tau tangles or amyloid plaques.

 

Those of us who are familiar with the ignoring of evidence that contradicts mainstream dogmas recognize this as routine, cognitive dissonance in the service of mainstream denialism.

“The scientific method” — it’s just not used, e.g. in Alzheimer’s Disease

Posted by Henry Bauer on 2014/07/17

Alzheimer’s disease is one of the dysfunctional knowledge monopolies mentioned in my book, Dogmatism in Science and Medicine  (pp. 108-9).

Decades-old dogma takes the cause of the disease to be the build-up in the brain of plaques of amyloid protein. However, a mass of actual evidence indicates that theory to be wrong: there have been “hundreds of experiments casting doubt on the neurotoxicity of amyloid”; drugs and vaccines that act against the plaque have been ineffective; amyloid injected into brains of mice caused no symptoms. Yet researchers find it very difficult to get their evidence for other causes of Alzheimer’s published or to get research support for their work.

Rationalizations that try to prop up the amyloid theory are feeble and far-fetched, as illustrated by a fairly recent paean to a “breakthrough”:
“New imaging shows Alzheimer’s unfolding in live brains” (Andy Coghlan, New Scientist, 18 September 2013):
“The two major brain abnormalities that underlie Alzheimer’s disease can now be viewed simultaneously in brain scans while people are still alive”. Amyloid plaque has been observable since 2005 by PET (positron emission tomography), but now one can also observe “tau tangles”, and “tau lesions are known to be more intimately associated with neuronal loss than plaques . . . . tau tangles accumulate first in the hippocampus — the brain’s memory centre — at a time when the plaques are already widespread. . . . Previous research has shown that the tangles rapidly kill neurons and trigger behavioural changes. . . . [The new] images suggest that the plaques are themselves harmless, but help to advance disease by spreading the tau tangles from the hippocampus to other brain regions” [emphases added].

Note first that “the scientific method” * that so many pundits still cite and believe in states that a theory is discarded when the evidence goes against it. Here, the mass of evidence against amyloid theory has not broken the grip of the dogmatic knowledge-monopoly. Even as it is acknowledged that tau tangles and not plaques are actually closely associated with loss of neurons, and that plaques were present “10 to 15 years before there are symptoms”, the amyloid theory is still paid obeisance by suggesting that amyloid plays an essential role by “spreading the tau tangles”.

But since plaque pre-dates symptoms by a decade or more, surely it makes more sense to infer that plaque “may be neutral or even beneficial, perhaps attempting to defend neurons that are under attack” since “some amyloid can be found in the brains of most people over 40”.

The New Scientist piece is based on Maruyama et al., “Imaging of Tau Pathology in a Tauopathy Mouse Model and in Alzheimer Patients Compared to Normal Controls”, Neuron, 79 [2013] 1094-1108; the “et al.” stands for 24 additional names. That article begins, “Hallmark pathologies of Alzheimer’s disease (AD) are extracellular senile plaques consisting of aggregated amyloid β peptide . . . and intraneuronal . . . pathological tau fibrils, while similar tau lesions in neurons and glia are also characteristic of other neurodegenerative disorders” [emphasis added].
Tau tangles, but not amyloid, are known to be associated with a number of neurodegenerative disorders. Where was the need to invoke amyloid rather than tau as a cause of Alzheimer’s in the first place?
Those who question established mainstream dogmas are routinely called “denialists” — “AIDS denialists”, “climate change denialists”, and so forth. In point of fact, it is typically the mainstream thatis truly denialist: evidence denialist. As Max Planck out it long ago, old theories die only as their proponents also pass away; science advances funeral by funeral.

Scientism, the Religion of Science

Posted by Henry Bauer on 2014/06/09

Comparing unbridled, uncritical belief in Science to religious faith has been quite common.

The belief, faith, or ideology that science can deliver unquestionable certainty and that only science can answer all questions is called scientism.

Toward the end of the 19th century, Thomas Huxley practiced scientism quite overtly as he preached self-described Lay Sermons on behalf of the Church of Science [Knight 1986]. In more recent times, however, scientism has become recognized fairly generally as an unwarranted faith and its adherents do not usually bear public witness to it, dissembling usually by claiming only a rational adherence to observable facts — of course, “scientific” facts.
Nevertheless, common behavior and language use [Bauer 2001] reveal scientism to be a widespread, action-determining ideology; thus the phrase “scientific tests have shown” carries far more impact than “tests have shown”, implying that what is “scientific” is beyond doubt. Such honorific use of “science” or “scientific” is one of the marks of scientism listed by philosopher Susan Haack [2013/14]; other clues include aping the methods and approaches thought to characterize science; drawing sharp distinctions between science and “pseudo-science”; obsession with “the scientific method”; crediting science with the capacity to answer any and all questions; denigrating non-scientific modes of inquiry.

Comparisons of religion and science have largely focused on authorities and hierarchies, comparing scientific researchers to priests, and Scientific Establishments to Vaticans and other religious authorities. At least as significant in practice, though, for everyday matters including politics and social activities, is the similarity of the behavior of followers and acolytes of religion and the behavior of groupies and devotees of Science. Both accept their gurus’ pronouncements uncritically, unreservedly, in equally sheep-like manner, and both parrot those sayings without actual understanding of what they are talking about. Christian fundamentalists, for instance, profess the inerrancy of “the Bible” in blissful ignorance of the fact that there are many “Bibles” in many languages with many self-contradictions and mutual disparities. Environmental fundamentalists and left-leaning others describe global warming and its consequences in blissful ignorance of the pertinent facts, for instance that the greenhouse influence of carbon dioxide is much less than that of water vapor and about equal to that of methane, and that the official projections of future temperature are based on computer models that cannot explain the lack of warming during the last 15 years or so or the 7 or 8 cycles of changes over a range of 5-6°C during the last million years.

Human beings appear to crave certainty of understanding and have sought explanations of observable things and phenomena for as far back in time as we can see and infer. Knowledge about themselves led humans to interpret natural phenomena anthropomorphically, in terms of powers and actions of spirits and super-spirits. The numbers of supposed Gods decreased over time, by 3 or 4 millennia ago shrinking among most people to just one all-powerful Being.
Seeking certainty via “Science” has a shorter history, in particular the “modern” science that is less than a millennium old and which waged explicit battle against Christianity in Europe in the 18th century.
That Science really won that battle is demonstrated by innumerable accommodations that most religions have made with the sciences, in extreme cases by casting religion as “scientific creationism” or its alter ego of “intelligent design”. That the victory enshrined Science as a faith held irrationally was pointed out by John Burnham (How Superstition Won and Science Lost, Rutgers University Press, 1987).

In the human quest for certainty, religion and scientism are two incompatible extremes: both hold certainty to be attainable, but by distinct and incompatible means: in the case of religion via faith and revelation, in the case of scientism via empirical investigation. In both cases, perfectly sound logic is used to draw practical conclusions from the premises. The two extreme worldviews do not differ in rationality, only in the premises from which inferences and implications and applications are drawn.
The space between those two extremes is very sparsely populated, by people who recognize that certainty is not to be attained and who try to live in that “existential” state. Whether acknowledged or not — to themselves as much as to others—, most people hold one of those two extreme beliefs; that is to say, they act as though they hold one of those beliefs.

Those who do not hold one of those extreme beliefs are not much appreciated by those who do. Acolytes of a different religious faith are denigrated as non-believers, pagans, heretics, and have been persecuted sometimes to the point of death. Those who do not accept what the scientific authorities claim are denigrated as ignoramuses, pseudo-scientists, denialists, and are persecuted by sanctions on careers and reputations.

Yet the premises of both religious faith and of scientism are demonstrably doubtful, not to say untenable.

Religious believers hold a particular faith despite the fact that most other human beings disagree with their claims: Every religion is a minority religion. If the Jewish God is The One, then the Christian One cannot be, nor the Islamic One. Moreover, within each of those three umbrellas there are several sects in deadly opposition. Catholics and Protestants have engaged in mutual genocide, as have Shias and Sunnis. Yet acolytes of any given sect within any of the Big Three are somehow able to regard their own beliefs as the only really True One. Religious leaders and their followers manage somehow to ignore the significance of the fact that informed, intelligent people adhere with equal certainty to other faiths. They remain blissfully ignorant of issues fundamental to their premises and doctrines and guides to behavior.

Quite similarly, Scientific Establishments and their followers manage to be blissfully ignorant of their own history, which demonstrates that in the long run they are always proved wrong as “science” “progresses” via Scientific Revolutions as well as less dramatic but significant continual modifications. Scientific Establishments and their followers willfully ignore the lesson that those whom they denigrate as denialists may well turn out to be the secular saints of future Establishments. By ignoring substantive critiques by competent “denialists”, they remain blissfully ignorant of the flaws in their specific doctrines concerning, for example, the Big Bang, prescription drugs, global warming, HIV/AIDS [Bauer 2012]. No matter how often Establishments claim to be evidence-based, even perfunctory browsing in the research and review literatures reveals that the mainstream consensus on many issues of considerable public importance is at the least seriously flawed, at the worst quite untenable.

Public media, politicians, and official agencies all kowtow to Scientific Establishments, with the result that public policies are often seriously, even dangerously misguided.
